account of their ])reocciipation. 



Alorcover, I do net tliink Melichar has correctlv referred 

 Ledropsis. I ha\'e not seen the types, but I believe that Rhotidus 

 and Rnbria are synon^nituis with this, or very closely allied. Th." 

 nymphs of Eogypoiia (=^ ? Coiiiptclasimis- ) and Rhotidus \ = ? Le- 

 dropsis) are very difi'erent. The former are vcr\- Hat. laminatelv 

 foliaceous. and exceedin<;i\- thin, while the latter are net unlike 

 the adults. 



Rhotidus ( = ? Ledropsis) . 



The female ultimate sternite is very similar in all the species 

 de.scribed h\ me. The posterior margin is slightly sinuate, with a 

 small median notch which is almost obsolete in Icdropsifoniiis. In 

 7'iridcscois, and inforinis it is obtuse-angled or somewhat round- 

 ed ; in horrcndus it is similar but mere acute; in nionstruin, 

 iiigois and flai'oiiuicuhTiUS it is distinctly rounded. 



Distant has described (1907 A. S. E. Belg. LI) : 



13. acqualis op. cit. 193. Queensland, and has transferred here 

 Lcdra tcUforinis, navicula and cuspidata Walker. This preoccu- 

 pies the "Rhothidus navicula" of Stal, from Queensland, which 

 is obviously not that of \\'alker ; for the Stalian species, I propose 

 the name of stali. 



Ledropsis 

 Distant has described : 

 I. froggatti op. cit., 192 Xew South Wales 



Distant has also described : 



Jukaruka (g. n.) typiea op. cit. 190 Queensland 



In the list of unknown Australian forms. I omitted Ruhria 

 sidiiiea (Xerophhea) Stal 1859 Eugenie's Resa. Ins. 288( Syd- 

 ney.) 



Tribe Stenocotini. 



This tribe differs from the Ledrini only in the position of the 

 ocelli, which are situated in elongate pits on the margin connect- 

 ing the vertex and the frons, and by the great emargination of 

 the vertex- basallv. T know only three genera, all Anstralian, 

 which have been analyzed on p. 368 of my former memoir.
